Summary: This study assessed the impact of polyethylene microplastics on aerobic granular sludge and found that the microplastics did not decrease the efficiency of biological treatment, but instead stimulated the production of extracellular polymeric substances and alginate. However, the presence of microplastics changed the morphology of the granular sludge and worsened the settling properties of the biomass.

Summary: Adsorption is an effective method for phosphorus recovery from sewages, and EPS-based and Fe-modified hydrogels showed high adsorptive capacity. The hydrogels could adsorb P via ion exchange and hydrogen bonding mechanisms, and had good performance under a wide range of pH conditions. Coexisting anions did not significantly affect the adsorption process, with the exception of CO32-. Ligand exchange was the major driving force for phosphorus adsorption.

Summary: Corrosion is a global problem in marine environments. This study investigates the microbiologically influenced corrosion inhibition (MICI) mechanism of Halomonas titanicae on two marine structural steels in aerobic environments. The results show that H. titanicae can inhibit the corrosion of both steels. The aerobic respiration mode of H. titanicae significantly reduces the dissolved oxygen concentrations, and the MICI mechanism goes beyond simply reducing the DO concentration.

Summary: The study assessed the recovery of phosphorus, nitrogen, methane, and extracellular polymeric substances (EPS) from aerobic granular sludge (AGS) wastewater treatment plants. About 30% of sludge organics are recovered as EPS and 25-30% as methane via alkaline anaerobic digestion (AD). It was found that a significant portion of phosphorus and nitrogen are present in EPS and can be recovered through chemical precipitation. Ammonium recovery is feasible from the AD centrate due to its high concentration.

Summary: This study investigates the relationships between granule stability, diameter, biomass retention capacity, and denitrification efficiency in Aerobic Granular Sludge (AGS) technology. The results indicate that granule diameter is not a reliable indicator of stability or biomass retention capacity. Promoting simultaneous nitrification and denitrification is found to improve granule stability. Ensuring coordination between diameter and denitrification control is crucial for AGS stability.

Summary: Microbial transformations are important for the Se cycle, as they convert Se oxyanions into elemental selenium (Se-0) nanostructures, reducing their solubility and toxicity. Aerobic granular sludge (AGS) has been studied for its ability to efficiently reduce selenite to biogenic Se-0 (Bio-Se-0) and retain it in bioreactors. In this study, selenite removal and Bio-Se-0 biogenesis in different size groups of aerobic granules were investigated. Large granules (>= 0.5 mm) showed rapid and efficient selenite reduction and Bio-Se-0 formation due to better entrapment capabilities. SEM-EDX analysis confirmed the formation of Se-0 spheres and their association with the granules. A bacterial strain, identified as Microbacterium azadirachtae, was found to efficiently reduce selenite under aerobic conditions and immobilize the resulting Bio-Se-0. The findings suggest the potential use of large AGS and AGS-borne bacteria in bioremediation of metal(loid) oxyanions and bio-recovery.

Summary: This study examined the long-term storage potential of aerobic granular sludge (AGS) by drying and storing it in zip-lock bags in a laboratory and storage room. AGS stored for different durations were reactivated and analyzed. The results showed that the granules became darker and smaller with each reactivation, while the settling velocity increased up to 25% after storage. Storing AGS for 1 day had the least impact on removal performance. It is possible to store the granules in fluctuating temperature conditions for up to 1 week, with the potential for recovery after continuous operation.

Summary: This study investigates the correlations among wettability, dimple curvature radius, and nucleation characteristics on nanostructured surfaces. The results show that nucleation sites are located in the interior of dimples. Increasing surface hydrophobicity or dimple curvature radius would make nucleation more difficult. The obtained critical sizes of nuclei from molecular dynamics simulations are larger than the results estimated by the classical nucleation theory. Additionally, increasing the dimple number benefits the nucleation probability and condensation performance.

Summary: Biochars derived from agricultural wastes were modified by manganese ferrite (MnFe2O4) co-precipitation and used as adsorbents for the removal of Cu(II) ions from water. The MnFe2O4-biochars exhibited rapid adsorption kinetics and significantly enhanced adsorption capacities. Complexation reactions involving carboxyl and hydroxyl groups in pristine biochars, as well as Mn-O and Fe-O groups in MnFe2O4-biochars, were identified as the principal adsorption mechanisms. The regenerated MnFe2O4-biochars could be reused for three cycles with a decline in maximum adsorption capacities.

Summary: This paper presents an integrated anaerobic-anoxic-oxic (A2O) treatment scheme for highly problematic wastewater from the production of PPS and its composite chemicals. The A2O process, utilizing anaerobic granular sludge blanket (GSB) and anoxic-oxic (AO) reactor, effectively removes COD, TKN, NH3, and S2 from the wastewater to meet the regulatory limits. With proper acclimation and design, the integrated A2O scheme offers a resilient and robust treatment solution for high-strength recalcitrant PPS wastewater.

Summary: The flourishing of anaerobic digestion highlights the importance of digestate valorization, which is crucial in determining the benefits of the process. Recently, digestate has gradually been perceived as a product rather than waste, in order to achieve the concept of a circular economy and maximize its benefits. Land application is the simplest way for valorization, but legislative restrictions and environmental concerns necessitate novel valorization methods. This review outlines the current methods for solid/liquid digestate valorization, nutrient recovery, microalgae cultivation, and integration with biological and thermochemical processes. The proposed novel valorization routes and their challenges and prospects are discussed, with the integration of anaerobic digestion and thermochemical methods showing potential market value for hydrochar/biochar-derived products.

Summary: In this study, the covalent organic framework TpPa(OH)2 was used for the first time as a pH-responsive adsorbent for copper ions from water. The Langmuir adsorption capacities showed that the process was endothermic and entropy-driven. However, the adsorption capacity decreased when proton attacks occurred at a low pH value. The pH-swing technique increased the adsorption capacity by creating excess sites on the exfoliated layers.

Summary: The eco-friendly treatment of complex textile and dyeing wastewaters is a pressing environmental concern. This study examined an approach that utilizes different treatment paths and integrated anaerobic-aerobic processes to treat high-strength and recalcitrant textile dyeing wastewaters. The results showed that polyaluminum chloride precoagulation was effective in removing over 97% of suspended solids (SS) and more than 70% of chemical oxygen demand (COD) in the suede fabric dyeing stream. Hydrolysis pretreatment also proved successful in removing up to 58% of COD and 83% of SS in other low-strength streams. Additionally, the integrated anaerobic-aerobic treatment achieved notable COD removal of up to 99% from high-strength wastewaters. The anaerobic granular sludge process demonstrated several advantageous attributes, including high feed loading, a smaller footprint, minimal sludge production, and good stability. Overall, the integrated anaerobic-aerobic treatment provides a robust and viable option for highly contaminated and recalcitrant textile dyeing wastewaters.
